Of course, the present version of Peng can only compute
classical collision integrals,
and can only deal with monatomic gas binary mixtures,
although these functions are rare in computer programs
publicly available.
In the future, more functions,
e.g., computing quantum collision integrals [1]}, [2]},
dealing with polyatomic gases [3]},
and more flexible quadrature rules
(including doing the integration on multi-dimension sparse grids)
can be added in newer version.
